Abstract

CLOSED CIRCUIT INTERLOCKED IN PHASE. THE CLOSED CIRCUIT (10) INTERLOCKED IN PHASE PRODUCES A VARIABLE OUTPUT SIGNAL (V <051> <052> <053>) INTERLOCKED IN PHASE AND FREQUENCY TO AN INPUT SIGNAL (V <054> <009>). CONSISTS OF: VOLTAGE CONTROLLED OSCILLATOR (12, VCO); FEEDBACK PHASE DETECTORS (14, 17); AMPLIFIER (18); FREQUENCY DIFFERENCE DETECTOR (20); FILTER (15); SWITCH (22); AND INTEGRATOR (23) PRODUCING CONTROL VOLTAGE FOR THE OSCILLATOR (12).
